all the 20v engines ive ever looked at (about 6) have done the same thing so im assuming its normal. i checked the PCV's on all of them too...

Hmm... interesting. I'm guessing it must have to do with the bucket/valvetrain design moving a lot of air around. Cos I've checked my soarer and stagea and both don't even have the slightest hint of air from the filler hole. Could also be the PCV system. Maybe the other 2 engines were designed to have more vacuum (larger PCV valve) in the crankcase compared to the 20V.
But it's such a relief that it's not blow by and all signs point to stem seals now.
